摘要：
It has been shown that after long-term exploitation of collectors of superheaters in the conditions of high temperatures and pressure causes structurally phase changes in steel of 12Kh1MF. Degradation of material of collector takes place: disintegration of pearlite colonies, carbides spheroidizing, the amount of carbides is increased on grains boundaries. Localization of origin and distribution of operating cracks is set in material of collector of superheater. Cracks, as a result of corrosion of on-loading material, develop along boundaries of grains, abatement pores and inclusions of carbides.
